Excelent Job Trevor and you're right about the 14-42 it's almost as sharp as the 12-60 according the test on PZ http :

So take care of that little basterd as it's worth to keep.

Thanks Lou, I am discovering all sorts of things about my lenses recently and it takes a time to sink in but eventually I am starting to see the subtle differences. Cheap doesnt necessarily mean bad certainly as far as Oly is concerned.
